Mistaken Swallows: Understanding the Effects of Accidentally Ingesting Mouthwash

Most mouthwashes come with a warning label, explicitly stating that it is not meant for ingestion. However, it is easy to swallow mouthwash accidentally, especially for children who might think it is similar to other tasty drinks. Ingesting anything that is not food or drink, especially something with a potent chemical composition, can be harmful; mouthwash is no exception.

What happens when you swallow mouthwash

When you swallow mouthwash, it travels down your throat and into your stomach. Most of the chemicals in mouthwash are not suitable for ingestion and can cause intestinal problems such as nausea, vomiting, and diarrhea. Depending on the severity of ingesting the mouthwash, a person may also experience dizziness or lightheadedness.

Ingesting mouthwash can be harmful in both the short term and the long term. Swallowing even small amounts of mouthwash regularly can lead to a variety of gastrointestinal issues. Moreover, the long-term consequences of swallowing mouthwash regularly are not known, making it a potentially hazardous practice to maintain.

Mouthwash Dangers: What Really Happens When You Swallow It

Overview of the chemicals in mouthwash and their effects

Mouthwash comprises several ingredients, including alcohol, sodium lauryl sulfate, fluoride, and xylitol. Alcohol is a powerful antiseptic and also a drying agent. Sodium lauryl sulfate acts as a surfactant, helping to loosen debris and bacteria from the teeth and gums. Fluoride is the active ingredient that helps to fight tooth decay, and xylitol is a sugar substitute that also helps to fight tooth decay.

Detailed explanation of what happens when you swallow mouthwash

When you swallow mouthwash, the chemicals it contains react with the acidic juices in your stomach and can cause damage to the sensitive lining. For people with pre-existing gastrointestinal issues, ingesting mouthwash can exacerbate their condition. The amount and frequency of swallowing mouthwash can also affect the severity of the damage done. The resulting symptoms can be mild to severe, depending on the individual’s age, body size, and overall health.

Risks and dangers associated with swallowing mouthwash

Swallowing mouthwash can lead to a variety of health problems, including gastrointestinal issues, chemical burns, and allergic reactions. Ingesting mouthwash regularly can also lead to more severe health problems such as liver and kidney damage. The potential long-term dangers of ingesting mouthwash regularly are not entirely known, making it a risky practice to maintain.

The Harmful Consequences of Ingesting Mouthwash and How to Avoid Them

Immediate consequences of swallowing mouthwash

The immediate health effects of ingesting mouthwash vary depending on the chemical composition, the amount swallowed, and the frequency of exposure. Common symptoms include nausea, vomiting, and diarrhea. In rare cases, ingestion can lead to chemical burns or allergic reactions so severe that hospitalization may be necessary.

Long-term effects of ingesting mouthwash

The long-term consequences of swallowing mouthwash are not entirely known, but studies show that regular ingestion can have harm to the liver and kidneys. It can also alter a person’s gut biome and lead to gastrointestinal issues such as Crohn’s disease or ulcerative colitis. As with any product, following the usage instructions, and avoiding ingestion is the best way to prevent any long-term effects.

Steps to take to avoid swallowing mouthwash

First, always remember to keep mouthwash out of the reach of children. Secondly, avoid consuming anything else for 30 minutes following rinsing with mouthwash, as this will prevent the chemicals from mixing with other substances in the stomach. Finally, if you are prone to mistakenly swallowing mouthwash, try using a children’s mouthwash that has a less potent concentration or rinse with plain water instead.

Swallowing Mouthwash: A Not-So-Fresh Feeling

Unpleasant symptoms associated with swallowing mouthwash

Swallowing mouthwash can leave unpleasant symptoms in the mouth and throat. The alcohol in mouthwash can cause a burning sensation in the mouth, throat, and stomach lining. This sensation can persist even after vomiting or otherwise expelling the swallowed product.

How to treat symptoms if you have swallowed mouthwash

If you accidentally swallow mouthwash, you may experience immediate burning in the mouth and throat before further symptoms start. The first step is to rinse your mouth with water repeatedly to remove the leftover product. This will help to reduce any irritation caused by the mouthwash.

When to seek medical attention

If the symptoms persist after rinsing your mouth, seek medical attention immediately. Vomiting and diarrhea can lead to dehydration and further complications especially if left unmanaged. If you experience any swelling or difficulty breathing, seek medical attention right away. If you believe you have swallowed a large amount of mouthwash, especially if you are feeling unwell and unable to keep fluids down, call emergency services immediately.

‘Rinse and Spit’ vs ‘Swallow and Regret’: The Truth About Mishandling Your Mouthwash

Explanation of why it’s important to rinse and spit

Sometimes people assume that the mouthwash’s antibacterial properties are dependent on swallowing it, but this is not true. The essential ingredients in mouthwash, such as fluoride, do not require swallowing to be effective. The best practice is to always rinse and spit out the mouthwash instead of swallowing it. Doing so will still leave your mouth clean and fresh while avoiding ingesting any potentially harmful chemicals.

Comparison of the benefits of rinsing and spitting vs. swallowing

Rinsing and spitting are the optimal way to handle mouthwash. Swallowing mouthwash presents myriad health hazards, with almost no benefits. It is better to err on the side of caution and prioritize your health instead. Rinsing and spitting help to maintain good oral hygiene without any unnecessary risks.

Final thoughts and takeaway message

Ingesting mouthwash can be harmful, causing a range of immediate and long-term health effects. Always follow the instructions for mouthwash use and avoid swallowing the product. Taking proactive steps, such as keeping mouthwash out of the reach of children and rinsing and spitting, are easy and tangible ways to protect your overall health.


As an essential part of daily oral hygiene, it is essential to understand the risks and consequences of swallowing mouthwash. While it is easy and common to swallow mouthwash accidentally or intentionally, doing so presents a range of health hazards. It is crucial to prioritize your health and well-being by avoiding swallowing mouthwash and always rinsing and spitting it out. Take care of your oral health, rinse, and spit every time you use mouthwash.
